Cellular Respiration
Chapter 6
| Question | Answer |
|---|---|
| Food is ____________ matter that contains chemical energy. | organic |
| ______________must consume food that is already organic | Heterotrophs |
| The chemical energy found in food is directly usable by cells. True or false | false, is not |
| _________________ is the cell’s energy currency. | Adenosine triphosphate (ATP) |
| Cellular respiration is _____________ . | aerobic |
| Fermentation is _____________ . | anaerobic |
| C6H12O6 + 6O2→ 6CO2 + 6H2O _________ contains stored chemical energy. Energy is released when glucose is converted to carbon dioxide. | Glucose |
| The reactants of cellular respiration are ________ and __________. | glucose and molecular oxygen. |
| The products are cellular respiration ____________ and _____________. | carbon dioxide and water |
| Cellular respiration occurs as a series of steps. All but the first step occur in the _________________ | mitochondrion |
| ______________ is the first stage of cellular respiration. | Glycolysis |
| Glycolysis occurs in the _____________, not in the mitochondrion. | cytosol |
| Glycolysis occurs in two distinct phases | Energy investment phase , Energy harvest phase |
| During the energy investment phase, two ATP molecules are “spent” further energizing glucose. • This causes the sugar to become _____________ and ___________into two molecules, each with three carbons. | unstable and split |
| During the energy harvest phase, ______ ATP molecules are produced. Net gain of 2 ATP | four |
| ______________ is an electron carrier. | Nicotinamide adenine dinucleotide (NAD+) |
| After glycolysis is finished we are left with two molecules of ___________. | pyruvate |
| These two pyruvate move into the mitochondrion. Before the next major step (Krebs Cycle), the two pyruvate undergo a few small changes. the two pyruvate have become | acetyl co-A. |
| The ___________ Cycle occurs in the matrix of the mitochondrion. | Krebs |
| NADH and FADH2 drop off their energized electrons at the __________ ___________ ___________ | electron transport chain |
| ATP ________ uses energy from this gradient to produce ATP | synthase |
| In anaerobic environments, ______________ may be used as an an alternative method of converting food energy to ATP energy. | fermentation |
| In ___________ fermentation, ethanol and CO2 are produced as products. | alcoholic |
| In ________ __________ fermentation, lactate is produced as a product. | lactic acid |
| Krebs cycle produces ______ NADH, ____ FADH2, ____ ATP, ___ CO2 | 6, 2, 2, 4 |
| Glycolysis produces ___ ATP , ___ NADH, ___ ATP | 2, 2 |
| Pyruvate produces ___ NADH and ___ CO2 | 2, 2 |
| Fermentation uses the _____________ ____________ to produce two ATP from one glucose molecule. | glycolysis pathway |
| Fermentation is conducted primarily by microbes. _________________ and _______________ | Bacteria and Yeasts |
| One molecule of glucose yields ______ ATP | 36 |
| Fermentation is much more efficient than cellular respiration. True or fa;se | false |
| One molecule of glucose yields ______ATP in fermentation. | 2 |
